<p>A process, either continuous or intermittent, for the synthesis of 2-hydroxy 4-methylthio butyronitrile which comprises adding an amount of methyl mercaptan to a mixture of acrolein cyanohydrin and a basic agent, said basic agent being used in an amount such that the pH of a solution obtained by diluting said mixture twenty times with distilled water is maintained between 7 and 8, said methyl mercaptan being 5 to 50 percent in excess of the stoichiometric amount relative to the cyanohydrin. The excess mercaptan is eliminated and can be recycled or reused for the continuous or intermittent process respectively.</p> |
